"al: 1, GCNHBCTICU', SSIGNOB T0 THE SPENCER TUBBINE Be it known that I, ne. n. sfr-Nm, a.

` citizen of the United States, and a resident of Hartford, in the county of Hartford and State of Connecticut, have invented a new and Improved Hose Connection, of which the following-is a specification.

My improvement relates more espec1ally to the class of devices employed for connecting a flexible hose to a rigid part, and the oblect of .my invention is toprovrde a connection which shall prevent lrinlring of the hose and undue wear movement of the b connected parts; and a iirther object of the invention is to `provide a connection especially applicable to a hand tool which shall enable the latterY to be freely and readily operated, and at the same time prevent un due wear of the 'hose connected therewith; anda further object of the invention is to provide means for readily connecting and disconnectin Lthe parts. A form of device -in the use o which these objects may be attained is illustrated in the accompanylng drawings, vin which- 'Figure 1 isa view on enlarged scale, -in central lengthwise section, through one end of a tool -handle and an attachment showing my improved means for .attaching a hose thereto. Fig. 2 is a side view of the same, scale reduced. Fig. 3 is a side view of a conductor used in cleaning apparatus, and to which my device is especially applicable, scale reduced. Fig. 4 is a view in cross-section on the line ar-a of Fig. 1. Fig. 5 is a view showing the slot and recess for locking the part-s in engagement.

In the accompanying drawings the numeral 5 indicates a conductor, which is a tool applied tothe surface of a floor, fabric, walls and the like for the purpose of removing dirt therefrom by means oi a current of air passed through the conductor. @ne end is formed into a receiver 6 and the opposite end is adapted for the connectionA of a hose.'

Previous to my invention a hose has been secured directly to the end of the handle 7, producing a shorthand in the hose near its point of connection, and the various positions in which the conductor is placed and.A

Patented etal connection between the handle 7 and the hose. In carrying out my. invention I provide a pivoted elbow-- including a mouth pieceV 8 which is securedl to the end of the handle 7. In securing this member to the handle the latter is preferably inserted within the end of themouth piece 8, a recess 9 being formed in outer surface thereof. This 'recess is of a size to receive the bottom y1f) of a lock nut 11. A slot 12 extendsfrom the end of the mouth piece 8 to a'point underneath the center of the recess 9, and a stud 13, secured to the end of the handle 7, pro- ]ects through said recess and slotand is threaded for-the reception of the nut" 11.v

When the parts are in locked position, as shown in Fig. 1 of the drawings, the. bottom of the lock nut 11 is seated at the bot-tom of than the diameter of the bottom of the nut 11. When the parts are to be disconnected Jan. 17, 191i.V

the nut is .turned until its bottom is removed the recess, when the parts can be readily separated, the stud i3 passing out through .the slot 12.

'llhe hose inlet member 14 or the elbow `is pivotally connected to the mouth piece 8 by a joint packed against the escape of air. ln the form herein shown a groove 15-is made in the outer surface of the mouth piece 8 of the elbow, and another groove 16 is formed on the inner surface of the inlet member 14. A ring 17 of a size to t these grooves is employed for holding the parts in engagement. The groove 16 is of a depth equal to or slightly greater than the thickness o the ring 17, the latter being split as shown in Fig'. 4f. By expanding the ring it is located entirely within the groove 16, so that theend of the mouth piece 8 may be passed into the inlet member 14C. The end of the mouth piece may be beveled, as shown at 18 in Fig. 1 or the drawings, to readilyperrcit the engagement or the parts.' `When the grooves .are placed opposite each other the n ring sprlngs lnto. the position shown in'Fig.t 1, securely locking the'parts against disen# ga ement.

ofthe elbow, these parts being shown in secnipple 19 for the receptionof ahose vremoval tion and being lettered the sameas hereinbefore described. The stud V13 is provided with a stop secured to its outer end and within a recess 21 in the lock nut 11.

The material taken up by the nozzle 6 A lwhen the tool is used as a suction pneumatic `to secure by LettersPatent is '1. A pair of conducting tubes ada ted vto fit together telescopically end to en a recessed seat formed near the end of one of said tubes, the tube being slotted from its end to the said Seat, a screw threaded pin carried bythe other tube and arranged when the tubes 'are fitted together'to enter the slot, a nut upon the said pin adapted when screwed down tofset into the said seat, the nut yhaving a recess in' its outer face, and ahead at the end of the pin ada ted to' enter the recess'in the -nut when the atter is screw ed outward upon the pin. l

2. The combination with a pair of conducting tubes adapted-to t together telescopically end to end, of a rib formed near the4 end of one of said tubes andarranged to form a seat, the said tube having a slot eX- tending from its edge and terminating within the rib, a pin carried by the other tube arranged to extend through the slot, the nut provided with a'recess arranged to en age the said pin and rest in said seat for loc the two tubes together, and a stop on the free end of the pin adapted to be received in the recess in the nut for preventing the disengagement of, the nut from the pin, substan-v tially as set forth'.

3. In a pneumatic cleaning dev-ice, the combination of a hand tool having at its outer end an attachment adapted to be applied to the surface to`be cleaned, a hose or conducting pipe, an elbow connecting the hand tool and ipe, the said elbow com rising two curved) parts, the opposite en s of each partv opening in directions substantiall at right angles'to each other,-and arrange yto telescopetogether, and means between the -telescoping portions of the two parts for locking them together, while permitting one of them to swivel. y

4. In' a pneumatic cleaning device, the combination of a hand tool having at its outer end 'an attachment adapted to be applied to the surface to be cleaned,- a hose or conducting pipe, the said parts, hand tool and hose being adapted to lie in planes parsov allel with each other, an elbow connecting v the hand tool and pipe, the said elbow comprising two curved pipes, the opposite ends of each pipe opening in directions substantially at right angles to each other 'and one of said pipes being arranged to fit closely inside of and lieparallel with the inner wall of the other pipe whereby there is formed a joint whose axis is at substantiallg;7 right angles to the aforesaid parallel planes, and

locking the pipes together,` while permitting one of them to swivel. l
